Share-Based Compensation Recognition and Estimates

The principal assumptions the Company used in calculating grant-date fair value for stock options and SARs were as follows:

	Three Months Ended March 31,
	2013	2012
Risk-free interest rate	1.0%	0.9%
Expected volatility	42.6%	43.4%
Expected dividend yield	1.5%	1.3%
Forfeiture rate	5.0%	5.0%
Expected life in years	5.3	5.3 - 5.6

Risk-free interest rates are based on U.S. Treasury yields in effect at the time of grant. Expected volatilities are based on the historical volatility of the Company’s common stock and the implied volatility from exchange-traded options on the Company’s common stock. Expected dividend yields are based on the per share cash dividend paid by the Company. The Company uses historical data to estimate option and SAR exercises and forfeitures within the valuation model. The expected lives of options and SARs granted represents the period of time that the awards granted are expected to be outstanding based on historical exercise patterns.
